### 一.安装zookeeper ###

--------------------

1.  **在线下载zookeeper** 
    
        wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz
2.  解压该压缩包
    
        tar -zxvf zookeeper-3.4.14.tar.gz
3.   启动zookeeper
    
        1.在zookeeper的目录中找到bin这个目录，zookeeper启动脚本就在这里。
        查看都有什么命令
        bin/zkServer.sh
        启动
        bin/zkServer.sh start
    
    ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI0NjA3ODM3_size_16_color_FFFFFF_t_70][]**注意：默认的/bin/../conf/zoo\_sample.cfg,我们需要把这个文件重命名为zoo.cfg，不然启动不成功**
    
        重命名
        mv zoo_sample.cfg zoo.cfg
    
     
4.  查看启动是否成功，如下图表示已经启动成功![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI0NjA3ODM3_size_16_color_FFFFFF_t_70 1][]
5.  需要知道的zookeeper配置信息：

*      # The number of milliseconds of each tick
        #zk服务器的心跳时间
        tickTime=2000
        # The number of ticks that the initial
        # synchronization phase can take
        #投票选举新leader的初始化时间
        initLimit=10
        # The number of ticks that can pass between
        # sending a request and getting an acknowledgement
        #
        syncLimit=5
        # the directory where the snapshot is stored.
        # do not use /tmp for storage, /tmp here is just
        # example sakes.
        #数据目录
        dataDir=/tmp/zookeeper
        # the port at which the clients will connect
        #zk对外服务端口
        clientPort=2181
        # the maximum number of client connections.
        # increase this if you need to handle more clients
        #maxClientCnxns=60
        #
        # Be sure to read the maintenance section of the
        # administrator guide before turning on autopurge.
        #
        # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
        #
        # The number of snapshots to retain in dataDir
        #autopurge.snapRetainCount=3
        # Purge task interval in hours
        # Set to "0" to disable auto purge feature
        #autopurge.purgeInterval=1

###    二.安装kafka ###

--------------------

*  下载kafka
 *      wget https://mirror.bit.edu.cn/apache/kafka/2.4.1/kafka_2.13-2.4.1.tgz
 *  解压
 *      tar -zxvf kafka_2.13-2.4.1.tgz
 *  修改配置
 *      #表示broker的编号，如果集群中有多个broker,那么broker的编号需要设置的不同。
        broker.id=0
        #对外提供的服务入口地址
        listeners=PLAINTEXT://9092 brooder,
        #设置存放消息日志的文件地址
        log.dirs=/tmp/kafka/log
        #kafka所需要的zookeeper集群地址：
        zookeeper.connet=ip:2181
 *  启动
    
        bin/kafka-server-start.sh start config/server.properties
    
    缺点：console关闭后，kafka也会被关闭，换为后台启动就可以了
 *  后台启动
 *      bin/kafka-server-start.sh -daemon config/server.properties
